Well of course, or no one would even use this forum. But even at 850psi that 1mm bore cartridge surely won't satisfy your usual biscuit tin smiley face penetration test ?
I'm guessing this is all for a miniature contraption, but isn't that sidetracking on world domination ?

Don't start making rubber band guns Clockwork birds made of gold though...

I must admit at times I have thought of making a miniature artillery piece.

Lateral thinking, my friend - not directly useful for world domination, but potentially useful practice while creating the sort of tiny artefact the ownership of which certain individuals are willing to part with considerable sums for, something I'm becoming increasingly conscious of.

why not try to make an on-board fueling system, with a butane canister in the grip and a venturi inlet to the pump?
With a small diameter pump like that you have the possibility to reach high mixes Just find a way to make a reliable ignition system that's not too bulky.

A piezo is good enough for a mini but only for 16x or so. What might do the trick is hot wire ignition, the capability of making small cartridges with say threaded bases to make the wire replaceable for every shot would be an asset, especially because it avoids the hassle of heavily insulating high voltage wires.

The beauty of Sherline equiment is that you can go step by step... from a lathe + a milling column to a lathe + a separate mill to a full CNC equipment!
And without never loosing money because you can reuse almost all the accessories... and resell the left over (like say, the wheels when you go CNC) on eBay for fair prices.
